Finally, an inbox you'll look forward to. Agents sort your messages, draft your replies, and clear the grunt work behind the scenes, all in a client so well-crafted that email feels light, fast, fun.

Really loving the product so far! I barely need to adjust the drafts Upstream generates. The only thing I’d love to see improved is smoother switching between mailboxes without opening a new tab each time.
@vivien_p I'm happy to hear that you're enjoying Upstream! Would a shortcut to switch mailboxes be helpful or do you have another idea of what would work best for you?

@louislecat just when I switch from the top right button to another mailbox that is already open in another window, it opens this window instead of a new one. I often get 6+ windows open. A keyboard shortcut could be cool too.
Daily driver here. Dictation mode lets me just talk and it writes. And "needs reply" is brilliant: the draft is already there waiting, so I'm never staring at a blank page, but I stay in control of what actually sends. Rare to find AI email that assists without taking over. Congrats to the team.
I’ve been using Upstream and what really stands out is how natural the drafts feel — they actually sound like me, not like a generic AI reply. Opening a thread and already having a solid response waiting there saves a surprising amount of time. The follow-up nudges are also genuinely useful for keeping important conversations from slipping through the cracks. Congrats on the launch — this is one of the few AI email tools that feels built for real daily use.
Great product! I tested it and I'm pleasantly surprised by its effectiveness! It manages my emails very well, with highly relevant suggested replies that save me time—just reread and send! I haven't tested the collaborative aspect with my team yet, but the promise is there: working together on emails to provide the best possible responses, all while staying aligned with everyone, and all powered by AI. I highly recommend it!
So glad to have you as part of our early users Johan. Thanks for the support ❤️

Been using Upstream for a few months now and I can’t imagine going back to Gmail. The UX is so much better, and the inbox splits have made managing my emails so much easier
Congrats on the launch Upstream team! It’s the only product where I find myself hitting « send » most of the time without changing anything in the AI’s draft. It’s so much faster than having to prompt Claude Code or Codex, wait for it to find the thread, analyze, draft and answer, then re-write half of it manually

@vivien_p Got it, so switching mailboxes, but staying in the same tab would be the optimal experience?

Been using Upstream in beta and the drafts genuinely sound like me, not like AI assisted. The reply’s already waiting when I open a thread. Congrats!

@benjamin_lalanne1 We appreciate that Benjamin! Also there are quite a few of us in the office that use dictation too 🗣️🗣️🗣️

@greg_lpz Thanks so much Grégoire!! Are there any features that would help make AI replies even better for you?
